A Vallejo man was taken to a local hospital Monday for a possible broken arm after his sister hit him with a baseball bat, a Vallejo Police Dept. spokesman said.

The episode, which occurred in the 300 block of Winchester Street, at about 1:30 p.m. Monday, started when Helen Newton, 50, of Vallejo accused her 49-year-old brother, also of Vallejo, of stealing her beef jerky, Lt. Kenny Park said.

An argument then ensued, he said.

Newton then armed herself with a metal baseball bat and struck her brother on his arm, causing serious injuries, Park said.

The victim was taken to a local hospital for treatment and Newton was booked into Solano County Jail on suspicion of felony assault with a deadly weapon, he said.
